After a car crash, women are more likely to go into shock than men, even when their injuries are less severe, new research shows. “Women are arriving to the trauma bay with signs of shock more often than men, regardless of injury severity,” said study leader Susan Cronn, a researcher at the Medical College of Wisconsin in Milwaukee. “We need to look further into how and why this is happening.” For the study, her team looked at clinical injury data from more than 56,000 car crash victims — half men, half women.  Even though men had more injuries overall, women suffered more injuries to the pelvis and liver, they found. More importantly, women surpassed a shock index greater than 1.0 more often than men. This was true even for those with fewer, less severe injuries.  Healthy adults have a normal shock index between 0.5 and 0.7.  Higher numbers may be a warning sign of a life-threatening condition called hemorrhagic shock, in which blood pressure, heart rate and body temperature plummet. Often caused by heavy blood loss, it can be a predictor of premature death. “Our findings might mean that women’s bodies have less capacity to function when physiological changes occur, that some injuries might have more impact on female bodies, or that female bodies handle blood loss differently than male bodies,” Cronn said. “It might…  read on >  read on >

Combat veterans who suffered traumatic brain injuries due to explosive blasts may have markers in their spinal fluid similar to those of Alzheimer’s disease, new research finds. “Previous research has shown that moderate to severe traumatic brain injuries may increase a person’s risk of Alzheimer’s disease,” said senior study author Dr. Elaine Peskind, of the VA Puget Sound Health Care System and the University of Washington School of Medicine. “What is lesser known is whether mild traumatic brain injuries from military training and combat may also increase a person’s risk. Our study found that these concussions may indeed increase a person’s risk of Alzheimer’s disease.” Traumatic brain injury (TBI) is caused by a bump, blow or jolt to the head, an injury as in a motor vehicle crash, or in service personnel, blast and impact injuries. In a mild TBI, also known as a concussion, person may lose consciousness for up to 30 minutes. The new study — published online March 13 in the journal Neurology — included 51 military veterans who suffered concussions from at least one war zone blast or a combination of blast and impact injuries. They were compared to 85 vets and civilians who had not experienced a TBI. On average, those in the concussion group had experienced 20 blast concussions and two impact concussions.  Participants took thinking and memory tests…  read on >  read on >

Following a cyberattack on the largest health insurer in the United States last month, health care providers continue to scramble as insurance payments and prescription orders continue to be disrupted and physicians lose an estimated $100 million a day. That estimate was generated by First Health Advisory, a cybersecurity firm that specializes in the health industry, according to the American Medical Association (AMA). “This massive breach and its wide-ranging repercussions have hit physician practices across the country, risking patients’ access to their doctors and straining viability of medical practices themselves,” AMA President Dr. Jesse Ehrenfeld said in a news release. “Against the backdrop of persistent Medicare cuts, rising practice costs and spiraling regulatory burdens, this unparalleled cyberattack and disruption threatens the viability of many practices, particularly small practices and those in rural and underserved areas,” he added. “This is an immense crisis demanding immediate attention.” How did the crisis begin? The security breach was first detected on Feb. 21 at Change Healthcare, part of Optum Inc., which is in turn owned by UnitedHealth Group. In a report filed that day with the U.S. Securities and Exchange Commission, UnitedHealth Group told government officials that it had been forced to sever some of Change Healthcare’s vast digital network from its clients. It hasn’t yet been able to restore all of those services. In its latest update on…  read on >  read on >

Lots of seniors are regularly taking low-dose aspirin in hopes of preventing heart attacks and strokes, even though updated guidelines often advise against it. About one in four older adults take aspirin at least three times a week, according to results from the University of Michigan’s National Poll on Health Aging. However, many seniors who take low-dose aspirin may not need to do this, researchers said. Nearly three in five (57%) of people ages 50 to 80 who take aspirin regularly don’t have a history of heart disease, poll results show. Those folks should talk with a doctor before starting or stopping aspirin use, because current guidelines mostly call for daily aspirin in people who already have heart disease or have survived a stroke or heart attack, experts said. “Aspirin is no longer a one-size-fits-all preventive tool for older adults, which for decades it was touted as,” said Dr. Jordan Schaefer, a hematologist at the University of Michigan School of Medicine. “This poll shows we have a long way to go to make sure aspirin use is consistent with current knowledge.” National guidelines for aspirin use have evolved in recent years because the over-the-counter drug can increase a person’s risk of dangerous bleeding. Experts now weigh the risk of bleeding against the benefits of preventing blood clots that can cause heart attacks and strokes. Because…  read on >  read on >

For nearly a week, prescription drug orders have been disrupted at thousands of pharmacies as the largest health insurer in the United States tries to fully restore services following a cyberattack. The security breach was first detected last Wednesday at Change Healthcare, a division of UnitedHealth Group, and two senior federal law enforcement officials told the New York Times that the hackers appear to be from another country. In a filing with the U.S. Securities and Exchange Commission, UnitedHealth Group said it had been forced to disconnect some of Change Healthcare’s vast digital network from its clients, and it hasn’t yet been able to restore all of those services. Change Healthcare handles roughly 15 billion transactions a year, representing nearly one in three U.S. patient records, the Times reported. This latest cyberattack underscores the vulnerability of health care data, particularly the privacy of patients’ personal information. Change Healthcare helps pharmacies verify a patient’s insurance coverage for their prescriptions, and some reports indicate that some people have been forced to pay for their prescriptions in cash, the Times reported. Shortly after UnitedHealth discovered the security breach, the company shut down several services, including those allowing pharmacies to quickly check what a patient owes for a medication, the Times reported While national drug store chains like Walgreens report limited effects, smaller pharmacies tell a different story. “For…  read on >  read on >

People who’ve suffered a moderate to severe traumatic brain injury have a greatly increased risk of brain cancer, a new study of military service members finds. Brain cancer is relatively uncommon, occurring in fewer than 1% of people in the United States, researchers said. But service members who had a moderate or severe brain injury were at 90% increased risk for developing malignant brain cancer, according to analysis of health data for more than 1.9 million veterans. And penetrating traumatic brain injury — where an object punctures the skull and enters the brain — was associated with a tripled risk of brain cancer, results show. While this was observed only in the military, civilians might be expected to run similar risks from brain injuries, researchers said. “Traumatic brain injury is not only common in the military, but also in the general population as well,” said lead researcher Dr. Ian Stewart, an Air Force colonel and professor of medicine at the Uniformed Services University of the Health Sciences. “While these results may not be generalizable to the population at large, given that military cohorts are different from the general population in many ways, it is possible that more severe TBI increases risk in the civilian population as well,” Stewart added in a university news release. However, the study also found that mild traumatic brain injury —…  read on >  read on >
